Confusing tooltip when hover over a DataArray.hvplot.rgb Image

Hi,

I am new to hvplot. I was following the hvplot example available at https://hvplot.holoviz.org/reference/xarray/rgb.html
At the end of the example we can find a DataArray.hvplot.rgb Image. When I hover over it the resulting tooltip is strange, for instance RGBA = 4290429906. What does this number mean?...is it possible to extract the red, green and blue component from such number?...is it possible to customize such tooltip to show a tuple with the r,g,b components?, is it possible to customize the tooltip to also show the x and y coordinates formatted as integers (by default the tooltip is formatted as float)?

Thank you very much for your help!
