I have used the spot meter in my OM-2S, OM-3, and OM-4 with wide angles
(24, 21, and 18s) when shooting transparencies without compensation and
have never had any problems. Part of what you may e seeing is just the
fact that the 'spot' is measureing a larger area with a super wide angle
lens.

Thanks to all for your input.
So, it appears to be a systematic problem with wide lenses and spot
meter. I still do not quite understand why the two cameras I tested
behaved differently (the center-weighted and spot reading in my
OM4Ti/2-13 weere identical, but not in OM4/2-4). But, could be.
Vignetting could be a reason for the observed behaviour, but one fStop
difference between center-weighted and Spot reading seems a bit too
much vignetting (I did my test at f5.6).
Be it as it is, question is, can I use the Spot meter with wide angle
lenses at all, do I have to compensate?
