Anyone familiar with sunburn on paphs??

[NYCorchidman]

This is a complex hybrid (Pandemonium 'Shock Wave' HCC/AOS x Thunder Mountain 'Mornach Pass').
Its new fan has this reddish brown area on the tip of one of the leaves.
I read plain green leaved paphs need more light than the mottled leaves so I put it where it gets about one hour of direct afternoon sun, maybe this caused sunburn?

I've never burned paph leaves so I don't know what sunburns should look like on these guys.

Maybe it's some other issue.
Someone who experienced this similar pattern, let me know.

If the area gets worse, I will just trim it off and see if the browning occurs again.

The flower pic is from december, but for eye candy.

hmm - I have slightly burned a strap leaf paph, and the area burned was whitish. That could be a bit of burn Hopefully someone else can say definitively

I would also guess burn, but I'm not sure.
