It should be checked at different V/div settigs, comparing normal and hires mode at each V/div.

Not every possible V/div setting, but not only at 1mV/div either.
Maybe 1mV (already done), 100mV and 1V.
Also try changing the horizontal timebase, see if Hires works better/worse at different settings. Try and find anything interesting.

The mathematics behind Hires mode are very simple, it's hard to imagine why it wouldn't work.
Then again, there must be a reason why it wasn't in there on initial release.

single-shot mode, force trigger

100mv / division
