What is a good reason to tell clients who want their logo to be always included in every screen that it shouldn’t be done for a mobile app?

Just as the title says, I'm not a fan of always displaying the logo at the title bar of a specific app. I sometimes come across a client whose concept screens are like that. What would be a good reason to tell them why it shouldn't be done? They usually want their branding to be emphasized all through out the app and I'm not confident as to what I can tell them to avoid it.

Reasons that I can think of are:

  1. It would consume screen space.
  2. Branding can be expressed in other ways like button color, etc.
  3. It would annoy the user ( as the trend is logo can only be seen at the start )
  4. It is a website thing.

Though with these reasons, I'm kinda anxious that the client would tell me:

  1. Color and layout is not enough
  2. I want my logo to be remembered
  3. The logo would be an indication that they are using the app.

Any insights would be nice regarding this problem, as I am not sure myself what would be the best solution for it. Thanks in advance!

edit:

I also noticed that it is a trend of consumer apps to only put the logo in the title bar when they are at the start of the app, anyone know what the reasoning behind this is?
