I would say for the most part yes, they do but they can adapt...
my reasoning is, this.. On a Sport shot, the backends tend to be DRY, so while they are burning a groove in the lanes, they dont have to really "work" the ball alot to make it hook...
On a THS, the backends might not be as DRY, depending on how often or well they are stripped.. So they might have to work the ball more and thats when they encounter the wet/dry.
Now the old bowling alley I bowled at, has a Regional Pro for the GM. And he averaged about 235 for the league he bowled on, while other house hacks were also around 220 to 230.. During one City Tournament, I was on the same pair for the team event as said pro, and The House condition @ where we bowled at was a very heavy oil condition.
While he struggled to carry, IE leaving weak 10's even a pocket 8-10!! and various other odd pocket hits he should of carried. the rest of us bowling on the pair had no issues with scoring/carrying.. I end up shooting a high 600, while said pro, i think shot 590..maybe, And he didnt miss the pocket the whole time.
But yet, I seen him bowl a Regional Stop, and for the 10game qualifier he averaged about 250.. I myself averaged 190....
