You mean scientifically?

Sample size = 1, total ad time most certainly increased.

The last 10 videos I played had 2 ads, one short unskippable (10s, not 5s), and one long that wasn't skippable until a long time had passed (like 30s). It was the style of ad that was a short-length video that was in itself somewhat captivating. I think I went something like 10 seconds into letting me skip, because it was about smart homes and I thought it was interesting.

Ads are truly a pest. Especially when they work.
