If I remember correctly, the Grissom set involved no rearrangement of the consoles as was done for the Reliant.
Not exactly clear on what you mean here; Are you saying, "No rearrangement from the way
Reliant was configured" or "Was not rearranged extensively from the
Enterprise set-up as was necessary for the
Reliant portrayal"?
Regardless, despite the significant shifting of stations to depict the
Reliant as a distinct Starfleet ship, the
Enterprise stations actually managed to get rearranged in every one of the first three films. There is the most obvious shifting of the science station between TMP and TWOK (which had its own subsequent consequences for other stations), but there was also a subtle reversal of two stand-up stations on
Enterprise between TWOK and TSFS. Picturing that post-TMP bridge from above, the two stations just counter-clockwise of the science station actually flipped between films. This might have just been a leftover of some of the
Reliant attachments (the "Dyno-scanner" next to the science station), but the
Grissom line up is indeed the same as the
Enterprise from the same film, just not the same as TWOK.
Instead, the captain's chair and the helm console were turned around and were, in essence, facing the rear bridge console seen behind Kirk in both TWOK and TSFS. That's why no viewscreen was ever shown. It was behind Esteban's chair.
Well, naturally! But still very clever.
This is, of course, the out-of-universe explanation for why everything on Grissom's bridge looked the way it did.
Actually, I think things were even more askew than that. The central stations were clearly reversed in direction, but they were probably set more diagonal than the conventional setup, as well as being significantly crowded toward that actual viewer area. The backsides of the captain's chair and helm/nav chairs were probably facing the station just clockwise of the main viewer. In this shot of
the helm officer (she
is the one that replied to the standard orbit command) film production was able to keep the main viewer barely out of sight, probably made possible by a more diagonal adjustment.
Of note, why does the
Grissom's navigator always
look stoned?

Heh. Probably wondering why they're always facing the wrong direction?
