Their latest statement says it will only have the level of stealth permitted by the US Government for export – an important issue for all stealth exports, by the way – and the level of stealth will only be comparable to fifth generation aircraft ‘such as the F-35’ from the frontal aspect. In other words, it’s only LO (not VLO) and only then in the head aspect and (these are my words only and I could be wrong) optimized against the air-to-air threat. Regarding the export issue, I think they were granted a license last year.
I doubt the f-15se will be the same as the f-35, do you have a Boeing link for that?
I can only find that they aren't claiming it on slide 5

The F-35 is VLO according to DoD, I can give a link if needed
