Do i need to buy Sekonic`s lumidisk?

Hi,

I am shoot wall artwork (paintings) on my small office using 2 flash strobe.

Painting size is usually between 50cm and 120cm length.

and i bought second hand Sekonic L-308S recently.

That is working well but i get to know about Lumidisc.

In documentation, The Lumidisc is used to measure the light falling on green-screen walls, paintings or flat art. It is also used to adjust lighting ratios with multiple light sources or when taking Lux and Footcandle measurements.

I am confused because I cant find any informations or samples to usage for lumidisc on Youtube.

Is that really need to me? will measurements change a lot? I am not measure Lux or Footcandle.
