No, the Size you showed is the largest for this font on the DM42 and two steps smaller as the DM41X font.
So what you want is a LARGER font. How about restricting your focus on the real issue here?

No, ask an optician and do an eye test. The DM41X font allows me to differentiate all Numbers without reading glasses, the DM42 doesn't.
Funfact: Even in 2021 most laser gauges or medical thermometers, even head-up displays in cars or fighter jets use segment fonts (and probably not because they are difficult to read).
Kindly indicate which of the following numbers ( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ) is causing you problems, to the point of confusing them, in the DM42 largest font. I am genuinely curious.
If distinguishing them is really an issue, how do you deal with the fact that the captions around and on the keys are MUCH smaller, and not "segmented" (though admittedly, they are razor sharp since they are silk screened)? And what is your point in looking at those without reading glasses? Are you so vain as to refuse to wear glasses? I am 7 years your senior, and ever since my hypermetropic, 20/15 vision decided to go presbytic a decade and a half ago, had to start wearing glasses. I am sure the experience is shared by many, but instead of making a fuss, we wear the darn glasses. Act you age.
And as far as laser gauges, medical thermometers and head-up displays (in cars*) are concerned, they will get by with segment displays because a 7 segment numeric element is cheaper and simpler to control than a 35 dots matrix, let alone the 260 dots rectangular area dedicated to one character at the current largest font setting on the DM42, and that they never have to display anything but a very restricted set of characters.
*For aircraft, the HUD uses either a raster projection display, or a vector one, and a collimating system so that focus is pushed to infinity. Ultimately, they are still pixelized, as the following high resolution picture of an aircraft HUD shows (lines that are not perfectly horizontal or vertical will show a jagged edge). Any claim of apparent smoothness is due to anti-aliasing.

The resolution of the Display is not high enough to show e.g. clear curves. You can see it easy on the o or e. The segment font looks raser-sharp.
But the DM41X font is
STILL going to
NOT be 'segment'. It is a pixelized approximation of what the original segments looked like. You gain
NOTHING in terms of sharpness.

5) If you want an "original experience", use an HP-41.
See #2, this was one important criteria by building this calculator (and for me to buying it).
BTW If there is a new HP41CV with a USB interface at an acceptable price, I would like to use it. The currently best choice as a replacement is a DM41X.
Well, get yourself one of these then (but your will need deep pockets):

Of course, it only has a serial interface, so one would need additional hardware to interface with an USB; but hey, the HP-41 predates the invention of USB by almost two decades anyway, so you would still not get it either.
Or is your definition of "acceptable price" always going to be 200€ less than whatever is out there?

No one here seems to be complaining about the DM41L font?
I did the biggest complaining: complete lack of interest. On the other hand the DM41X I bought immediately. Next to the terrible keyboard layout this was the second important reason that I was not slightly be interesstet in the DM41(L).
Complaining about what? The DM41L font? That calculator was introduced in 2015; and you complained when? After it was designed, put in production and offered? What were you expecting, that Swiss Micro would be able to track down the original maker of the HP-41 display (which most likely had been out of production since the HP-41 line was discontinued in 1990 anyway) and source a new batch, just because you refuse to wear your glasses?
