I'd suggest holding expectations for now.
We haven't seen most of brigades of the offensive force yet - not even the majority. So majority of Ukrainian strength, wasn't committed yet. To be fair, however, the strongest of those brigades (and the only ones which more or less deserve the name mechanized), were probably meant for exploitation.
On the other hand, we've seen 3 of them, which isn't exactly little.
No, those aren't probing attacks; combat battalions of 33rd (apparently those are its leos) and 37th suffered very heavily, maybe to the point of losing offensive capability. Those are not the end of that Ukraine can muster, either.
Current results are beyond disappointing - Russian mechanized BtGs at Ugledar failed to pierce through defensive lines; but here, as far as i understand, Ukrainian motorized ones can't even fully get through huge no man's land, at best reaching screening positions of the Ru defense.
That's not exactly impressive.
Also, in practical warfare, Leopards seem to be incredibly vulnerable.
