@rapolas I really use Twitter in the browser because I find it more comfortable and it even works more smoothly than the application. Then I think, so that I have one more application on my phone if using the browser I have everything I need. Opera gives me everything I want to use Twitter, even push notifications!.
Regarding the dark mode, I don't just talk about Twitter, I would like to be able to configure black Amoled mcdvoice for all web pages.
Unfortunately it happens very often. I agree with the dark mode is very well achieved and looks beautiful, although I am a fan of black Amoled. I hope you can solve the problem of images in dark mode soon
