UPDATE:

the two HDTV broadcast are temporally and spatially aligned; the russian version seems to have more details/grain intact, but also more compression artifacts; scandinavian version has less artifacts, but also less details and seems a bit too much waxy; if overlaid, result is better than single version; I thought to add a grain plate to improve perceived detail level.

russian HDTV (note residual logo, bottom left, and black drop outs, left side near the circular door):
