Were any third party games at E3 confirmed to be native 4K on XBOX?

did anyone really feel the difference between checkerboard 4k and native 4k during the gameplay?
Digital Foundry had to freeze a scene, and perform a extreme zoom to show the difference...
Its known that chekerboard 4k is much better than upscaling, so theyre fine. both ps4 pro and xbox one x.
