Agreed. The Enterprise one just irks me. It bothered me at the time. Particularly when they had the D5 design later - which I really liked. Stuff like the ENT D7 takes me out of the show.I'm not sure that is really a continuity issue though. It just suggests the Klingons stick with what works. The D7 in Discovery is the continuity issue, and no amount of "visual reboot" changes that.
Also yes the DSC D7 raises far more questions than it answers.
