Pixel size has no influence on the distribution pattern, only on your perception of it.
So your photon knows in advance how big the receiving sensor is going to be? A small child might argue that an elephant ceases to exist if he shuts his eyes, but the elephant thinks otherwise.
What we know is that the diffraction of photons depends on the associated wavelength of the photons and the spatial frequency of the diffraction grating, not on the area of any subsequent detector.

What the detector shows is irrelevant. The elephant stays in the room and so do its fleas, whether I wear my spectacles (so I can see them) or not.
I think we can assume the laws of physics apply even in the absence of a detector.
It is I think obvious that a detector cannot resolve detail smaller than its granularity. So what?
So you allege that a photon knows in advance what it is going to encounter. That really changes all we know about physics.
So whatever it is, interacts before it interacts, then decides where it is going to go when it interacts?
You have asserted that it can travel backwards,

In this video I set out to measure an effect called "Photon Bunching". Photon bunching is phenomenon characteristic for incoherent light It can for example be used to measure the angular diameter of stars and was discovered by Robert Hanbury Brown and Richard Quintin Twiss in 1954.Video chapters:0:00 Introduction0:42 Brief description of coherence4:01 Description of the experimental setup10:17 Aim of the experiment11:40 Main result12:25 Explanation and discussion13:10 What is a photon?16:10 Relation field amplitude / intensity / probability 22:17 Second order correlation function described 25:23 The Hanbury Brown & Twiss effect27:25 Trying to measure g(2); failure and succssAll wave animations in this video were produced using a Python script supplied by @DiffractionLimited . Thank you very much Manuel for supplying me with this tool.Third party imagery and clips:14:35 Image standard Model of elementary particles: Source WIkipedia14:55 I got the "face slap" clip of a channel named @neilsandwichtv5186. Not sure if this channel indeed is the copyright owner. Contact me if you have more info on this.13:36 I used a few very short clips from @ArvinAsh as illustrations of the particle presentation of light and photons. Arvin makes very high quality content on various scientific subject. But I guess his photon visualizations leave some room for improvement (;-).
