A higher octane in an engine rated for a lower octane shouldn't negatively impact its performance. Lower octane in a higher octane / compression engine is what will have negative effects. Curious as to how you saw a positive difference going back to 87.
That was always my understanding as well. But it never seemed to run right with the Trufuel. It wouldn't get up to full RPM's and would bog down easier. Ran like a top on 87. I assumed it didn't have enough compression to fully burn the higher octane Trufuel, but I really don't know.

Not as much to do with octane but the nature of canned fuels in general. They all will produce less power than fresh regular gasoline/gas-oil mix due to the fact that canned fuels are a mix of very refined compounds but overall has less volatility than gasoline. You are trading peak performance for convenience which is why I run my equipment on my own mix and only run canned fuel in the last tank of the season. My blower sees almost year round use so I use Echo canned fuel in it during the off season but it definitely is down on power while doing so.
