It is thoughtful of you to ask. I cannot give you a definitive answer, but generally I cannot imagine there would be a problem. You took the photographs on the ground and with the captains permission. Nothing in them should be of proprietary significance to the company or likely to cause them damage.
Some countries don't allow photographs to be taken on their airports in certain circumstances, but if these are general photographs of the flight deck of a Boeing 787-800 I cannot really see any particular problem.
For someone to care, there would usually be a compelling reason. From what you have said that wouldn't appear to be the case.
