Here is a comparison that Dyver Phycad did: Version 23.02 - Catalyst - General Feedback - #367 by Dyver_Phycad
It doesn’t look like much, but it is different on a live setup if you don’t have the picture zoomed into your face and if you have set your neocom to small, then with the darkened grey there is just not enough light coming through the icons to be comfortably visible. So the impact of grey vs. white is on the very border of making it unplayable.
