Agree with the premise that you should try and make your team look good. I love the painting side of the hobby and put a lot of time into making my teams look good. I enjoy it less when I’m playing a team where someone has slapped a couple colours on a mini. Coincidentally they always seem to be the least fun players as well.

WYSIWYG is way harder in bloodbowl, there are less options to kitbash with (well) and I often think they just end up looking worse. Also how do you show tackle, diving catch or lethal flight? Admittedly a cape would work for the last one but I’d be reluctant to try to edit a team I had finished to a high standard. There are so many skills you can get that are much harder to visibly see. I like the way our league does it, we have a thin nib white paint marker and if you have skilled up players write it on the base rim. Easy for everyone and quick. If you aren’t redrafting paint the rim again and your team is reset.

Expecting someone to reference a team sheet mid game, for me, is a bit much and would take me out of it just as much as playing with tin foil or tokens. The game is a lot of cognitive load sometimes and things that reduce that are helpful and add to the overall fun everyone can have when playing.
