Can Buddha be insulted by disrespect?

I found a video about Leshan Giant Buddha and was watching it with my family. In that video some workers were cleaning the statue's head while walking on it (it is a giant statue) - and my family members were surprised that people walked on Buddha's head, because to them that looked disrespectful. I replied that it's not a real problem, because Buddha does not have attachment to respect and would not feel insulted. Was I wrong or is this correct? The Buddha would never cling to such concepts like respect and feel insulted, right?
