Until something can transcend outside of the wrestling bubble broadly into pop culture and bring in people who aren't your typical wrestling viewer, there will be no boom period.
Any increase in viewership right now is likely just largely lapsed wrestling fans or people who were watching WWE and decided to start watching AEW, New Japan, etc. and vice versa.
If you like wrestling it's a great time to live in. Outside of the Bloodline stuff, there really isn't anything going on that can potentially transcend outside of the wrestling bubble. And for as long as this Bloodline stuff has been going, it still hasn't transcended broadly into pop culture, so at this point I don't really see it doing that.
And you need multiple things going on that can transcend outside that wrestling bubble to get that boom period going. Like back in the Monday Night Wars you had high-level stories with nWo, Stone Cold, DX, Rock, etc.
What's the second best thing going now story-wise or at least was going on? Bray's dumbass shyt that never pays off? Dom cosplaying a wrestling version of Prison Mike? Scissor Me Daddy Ass? Everything a very significant dropoff from the Bloodline that no one outside of wrestling is going to give a shyt about.
