The most obvious differences between Cherry and Helvetica Rounded Bold are ^, *, G, and t. The t's in your renders all look correct, but I'm still seeing the Cherry versions for ^, *, and G. This is what I got from
Linotype's website.
My previous Infinikey caps used those exact legends (on top of an OG Cherry WoB set for comparison; sorry for the HDR):
Note the wide ^, tail-less G, and six-pointed * on the Cherry caps, compared with the narrow ^, G with a bottom tail, and five-pointed * on Infinikey.
The characters in your renders definitely look like the Cherry ones.
