I have searched on Lenovo's pages and cannot find any documentation that confirms that "Thinkpad Ultra Dock" docking station (in my case 40AJ0135EU) is compatible with the latests T490(s)/T590(s) series.
Does anyone know?

The 40AJ dock is quite new, introduced with the Tx80 series in 2018, so it should be compatible with the Tx90 series.
You can also check the Accessories and Options Compatibility Matrix (OCM). Download the first Excel document.

I already tried the compatibility matrix and also find docking station for your laptop on Lenovo's support pages but without success.
But like you metioned it is a newer docking station so it should work.
However, some shops selling this docking station mentions specific models for the T490 and T490s sub-models as seen in the example list below. Does this have something to do with the native screen resolution becuase it is the first time I have seen that there should be limitiations to specific sub-models?

All information you need are definately in the ocm document. Select the 'TP T' worksheet.
IIRC some old Thinkpads, especially the discrete gfx models, were not supported, because they missed the docking port.
This might be the reason why each specific model is included seperately in the list of supported systems. This is also the case in the ocm.
