It was significantly less odd to me after I saw it looked pretty much exactly like the original 35mm film references. Also the fact that the stated goal of KOTCS was to look like ROTLA, if taken at face value, makes it pretty much the opposite of odd.
Bulb-matching is a real thing. If you just scan the film on your typical neutral-to-cool flatbed scanner, it may look great--even more lifelike--but not like it looked in the theatres during its original run. Lots of older films have taken on a much more golden hue and muted palette after they went through the trouble of bulb matching. The Godfather films on BD, for example, look practically sepia throughout with the strong yellow cast, but that restoration was overseen by Robert Harris--and much as I like to armchair general things, I trust his judgment (on his own work, at least) that this is just "how it looked"--even if scans of those exact same sources using a neutral light source results in something that looks more like the DVD releases or television cuts, or even how that exact same film looked projected using a later-vintage bulb in the nineties.
EDIT: This does bring up a film purity question, though. If the films from this era were all projected with a heavily biased light source, which is the accurate color? Is the film in the can or the film on the screen definitive? I think a fairly strong case could be made that WOWOW may represent the colors of the film "in the can", which nobody actually saw until much later, while the Blu-ray represents the colors of the film "on the screen" which only looked that way due to the very yellow bulbs in common use at the time. IMO neither colors would be "wrong" or "not original", although only the yellowish ones could be fairly called "theatrical".
