(1) I have a 31" Eizo CG318-4K which I run in 2560x1440 resolution, also 125% and Aero. And with this higher resolution situation the text from EPG123 in the title bar does display.

It's on my other machine, which runs 1920x1200 and 125% and Aero where the EPG123 text in the title bar is missing.
(2) I have another legacy application, Clockwise, which I also have been running for many years and for which the text in the title bar (day) does or does not display. Interestingly, again on the 2560x1440 resolution Eizo the text DOES display.

Once again, on the other machine which runs 1920x1200 the Clockwise text in the title bar does not display.
