At least part of this is going to be the resolutions at play. In windows 95 era you were dealing with 640x480 resolutions. Maybe 1024x768. Modern displays are doing a lot more than that. 1920x1080 at a minimum.

Beyond that, in windows 95 in the extreme you could be looking at only 16 colors. 256 colors was also not uncommon. 16bit colors became common in the windows 98 era.
