4.15 tonemapper - is it possible to simulate old effects?

I stumbled upon this thread for obvious reasons - wanting to retain ‘core’ color of the material. I’m working on recreating real life object, the NBA Basketball shot clock to be precise. Yes, my project is much more on the physically accurate side rather than the artistic side, but ‘artistic’ tweaks are more than welcome.

The solution that works for me so far is going into PPV Details -> Bloom: Intensity between 2 and 3 (currently set to 2.5), **Threshold left at default -1.0 **and then going into Advanced tab and tweaking Size Scale.
In order to have even more realistic result, I would probably have to make LED dots smaller and increase the Bloom Size scale to something like 10. It’s at 4 (default) at the moment.

I’m going to watch the video stream posted in this thread and do more research. I would gladly go back with results and conclusions.
