Can anyone ID my favorite monstera??

I got her a few years back in a runner grab bag from none other than Mick Mittermeier himself. For a while I was sure it was a lechleriana, but after doing some more research since it's been more mature, it seems that lechleriana (or at least all the confirmed specimens I could find online) keep their fenestrations much closer to the midrib. She also finally flowered, so I figured that could also help get a positive id.

Also as you can see from the second to last pic, it didn't start getting any fenestrations until it started to mature, which I believe rules out any form of adansonii.

Any help would be greatly appreciated!
